Keratoconus is a progressive eye disease in which the cornea, the clear front part of the eye, thins & bulges outward into a cone shape. This irregular curvature results in distorted or blurry vision, increased sensitivity to light & night blindness. Keratoconus typically begins in adolescence or early young adulthood & tends to occur in one or both eyes. If left unwatched & untreated, the condition can progress over time. Early diagnosis is important since treatments such as specialized contact lenses, cross-linking of the cornea or surgery may be used to preserve vision, prevent its progression & improve general visual clarity.
